Abstract

See full text

An improvement to the Waissi type opposed piston internal combustion (IC) engine is proposed. The engine has at least one pair of aligned and opposed cylinders with one reciprocating double-headed piston assembly in each cylinder pair. The reciprocating motion of the piston is transmitted to the driveshaft by a rotating crankdisk, which is mounted off-centered to the driveshaft. When the crankdisk rotates, the flat linear sections on the outer perimeter of the bearing ring prevent the bearing ring from rotating, hydrodynamic lubrication conditions are created on both the outer flat linear interfaces and the inner perimeter of the bearing ring.
